Nevertheless, we had a very enjoyable stay for a week in July. The room was very spacious for thee people, with high ceilings and windows that opened, and very quiet, despite its location right over the front entrance. The mini kitchen was great for breakfast, excellent grocery stores with partially prepared food in the vicinity made this an economical way of picking up the odd meal.
The room was well fitted out, with room for storage of suitcases, and could be kept tidy. The beds were comfortable. They offer you discount coupons at local restaurants at the front desk. There is even a vending machine that sells milk. They really have thought of everything.
My only quibbles - only combined shampoo/body wash was available, which wrecked havoc on my hair after 7 washes. And the internet is quite slow, which I understand is related to the availability in that part of London.
